Pressure delivery outlet in good faith for you to create affordable quality assurance we start talking about the design pressure delivery outlet load, the design load is too small or too small air volume or flow rate, the upper space temperature will become higher, it would come internal air temperature and fan all around ... usually install a pressure delivery outlet, the outlet what effect it simple to analyze the following:? If there is a situation of pressure delivery outlet fire effect, the emission of smoke blower on the inside will open a positive pressure fan or autonomous artificial fire disaster alert device will be independent of the motor is turned on, turned positive pressure in the house at the top of the tower fan and outlet pressure delivery outlet before the face, removing the inside air pressure between the front of the room exit stairs .
